10 Claims.

This invention relates to window operators; and has special reference towindows including a vertical series of sections supported for swingingmovements on horizontal axes from and to closed and open positions.

Objects of the invention are to provide an improved window including avertical series of sections supported by pivots extending from theirends through the vertical portions of the window frame, a verticallymovable rack bar in each side member of the frame for rotating saidpivots and thereby opening or closing the respective window sections; toprovide novel metallic sash structure for the window panes includingmetallic frame -members shaped and formed to maintain necessary anddesired rigidity indefinitely; to provide sealing Weatherstrip devicesfor maintaining sealed joints between the respective sections and alsobetween the sections and the window frame; to provide connectionsoperated by said rack bars for turning the pivots of the window sectionsto open and to close said sections; and to provide novel easily operatedmechanism for moving said rack bars vertically as required to open thewindow sections successively and to close them in the same order.

Another object of the invention is to provide improved'operatingmechanism for the window sections comprising levers connected with thepivots by which the sections are supported, vertically movable barshaving racks thereon for engaging gear segments respectively and atdifferent vertical positions of the rack bars in order to operate saidlevers and move the window sections, and means for sealing inweatherproof manner the respective window sections when they are closed.

Other objects will appear from the following description, referencebeing made to the annexed drawings, in which- Fig. l is an inner sideelevation of a window constructed in accordance with the presentinvention.

Fig. 4 is a similar View showing all but one of the window sectionsopen.

Fig. 5 is an enlarged view of one of the gear segments forming a part ofthe operating mechanism for each window section.

Fig. 6 is a side elevation of one of the cooperating lever members formovingthe window sections.

Fig. 7 is an enlarged vertical sectional view on the line 1-1 of Fig. 1,parts being omitted.

Fig. 8 is an enlarged horizontal sectional view on the line 8 8 of Fig.1.

Fig. 9 is an enlarged horizontal sectional view on the line 99 of Fig.1.

Fig, 10 is an enlarged sectional view on the line Ill-10 of Fig. 2,showing more clearly the connections for moving the window sections.

The window frame is mounted rigidlyin the proper opening in the buildingwall, and may include duplicate vetrical side portions each composed ofangular members I, 2, and 3, attached together and to the building wallat the sides of 20 the window opening, and having their-upper endsattached to the'rigid frame device 4 and their lower ends attached tothe rigid frame device 5.

A frame thus constructed provides vertical spaces 6 in the vertical sideportions and a space I in 25 the'lower portion thereof. The operatingmechanism for the window sections is mounted in these spaces and therebyconcealed and protected. A vertical reinforcing bar 8 is attached toeach vertical angular member I. The frame 6 further comprises angle bars9 attached to the members I, the top member 4 and the bottom member 5.Angle bars l0 (Fig. 8) are attached to the angle bars 9 at the sides ofthe frame, and channel-members ll (Fig. 7) are attached to the 35 anglebars 9 along the top andbottom of the frame.

Resilient metallic sealing strips I2 are secured between the inwardlyextended portions of'the angle bars 9 and ID at the sides of the frame,and have angularly extended arms l3 engaging the reinforcing bars 8.Resilient sealing weatherstrips M are attached between the-angle bars 9and II at the top and bottom of the frame and extend outwardly therefromfor cooperation with 45 the respective window sashes.

Each end of the respective window sections comprises a metallicstripbent to provide a sup? porting portion IS, an outwardly extendedpane abutting portion l6, anda laterally extended flange l'l contactingthe adjacent member I. The lower ends of the end members of each windowsection are connected by a metallic strip bent to provide a portion [8,an outwardly extended pane abutting portion 19, and a down- Wardlyextended margin 20. The upper ends of the end members of each windowsection are connected by a metallic strip bent toprovide an upperportion 2|, an inwardly extended abutting frame portion 22, and adownwardly extended flange 23 at the outer margin of the portion 2|. Areinforcing bar 24 may be mounted in the frame 22 wherever needed toprevent downward bending of the window sash. In instances where it isdesired to divide the longitudinal area of any window sash to receiveseparate panes of window glass, T-bars 25 may be attached to the lowerand upper horizontal portions of the respective window sashes (Figs. 1and 9). The window panes 26 are mounted in the respective window sashesagainst the abutments I6, l9 and 22 and secured in position by putty 21,or otherwise as desired. The upper portion 2| ofeach window sash,excepting the uppermost window sash, has attached thereto an angle strip28 constituting an abutment for the next adjacent window sash portionI8, while the flanges 20 of the respective window sashes engage theouter edges of the next lower window sashes when the window sashes areclosed, as shown in Fig. '7. Resilient sealing weatherstrips 29 areattached to the angle members 28 for close contact with the lower edgesof the adjacent window sashes when the windows are closed. Theseresilient weatherstrips 29 are in continuation of and in cooperativerelationship with the strips I2 and M. The upper portion of the windowframe includes an angle strip 39 cooperating with and extendingdownwardly beyond the top of the upper window sash at the outside toconstitute a guard and protecting device, preventing the passage ofwater and other substances inwardly above the upper window sash. A bar3| is attached to the lower frame device 5, has an abutment for thedownwardly extended flange 20 of the lower window sash, and cooperatestherewith to prevent inward passage of rain and other substances.

Each window sash is pivotally supported by a pair of axially alinedpivots 32 attached to the ends thereof and extending through bearingsleeves 33 attached to and extending through the reinforcing bars 8 andthe members I into the spaces 6. Levers 34 are rigidly attached to theouter ends of the pivots 32 within the spaces 6, and have slots 35receiving rollers 36 rotatively supported by levers 3'! supported forturning movements on pivots 38 attached to the members 42 within thespaces 6 (Figs. 2 and 10). The levers 31 are attached by welding orotherwise to gear segments 39, also supported for turning movements onthe pivots 38. By this construction and arrangement, the levers 3'! willmove the levers 34 when said levers 31 are operated from the positionsshown in Fig. 2' to the positions shown in Figs. 3 and 4 and beyond, andVice versa.

A vertically movable rack bar 40 is mounted for vertical slidingmovements in each vertical space 6 which are at the sides of the windowframe. Each of said rack bars 40 is formed with a series of spaced racks4| corresponding to the respective segments 39 and adapted to be movedsuccessively into and out of meshing engagement therewith. The order inwhich the racks 4| may be engaged with and disengaged from therespective segments 39 may be varied as desired, so that the differentwindow sections may be opened successively in any desired order and.Closed in the reverse order. These rack bars are mounted between andare guided by the levers 31 and guide elements 42 which are secured tothe members by fasteners 43 (Fig. 8). The lower ends of the rack barsoperate between guides 44 and 45 attached to the members substantiallybelow the lower pivots 32 (Figs. 2 and 4).

In each space 6 a sprocket chain 46 has its ends engaged with the rackbar 40 and is engaged over upper sprocket wheels 41 and lower sprocketwheels 48. The lower sprocket wheels 48 are attached to the ends of ahorizontal shaft 49 rotatively supported within the lower space A wormgear 50 is attached to the shaft 49 and is in permanent engagement witha worm 5| rigid on a short shaft 52 so that, when said shaft 52 isrotated, the chains 46 will be operated and the rack bars 40 movedvertically. A crank 53 is attached to the inner end of the shaft 52 sothat said shaft may be operated manually as required to open and closethe window sections.

As shown, the upper racks 4| will first engage the. upper segments 39and thereby open the upper window section. Next, the lower racks 4| willengage the lower segments 39 and thereby open the lower window section,the upper racks 4| passing out of engagement with the upper segments 39at the time the upper window section is in open position. At the timethe lower window section is in open position, the lower racks 4| passout of engagement with the lower segments 39. Thus, it is apparent thatonly the upper window section may be opened and kept open while theremaining window sections remain closed, or both the upper and lowerwindow sec-- tions may be opened and kept open while the intermediatewindow sections remain closed. Or, as shown in Fig. 4, the intermediatewindow sections may be successively opened and kept open by continuedupward movement of the rack bars 40.

When it is desired to close any or all of the window sections, the rackbars 40 are moved in the reverse direction to the extent required toclose the selected window sections in the reverse order to that in whichthey were opened.

It is now apparent that this invention attains all of its intendedobjects and purposes efficiently and satisfactorily; sashes andoperating mechanism are of strong and durable construction and may bevaried widely within the scope of equivalent limits without departurefrom the principle of the invention.
